Author:
Myroslav Mokhammad Abdeljawwad

Description:
This dataset provides daily air quality and meteorological measurements for Berlin, Germany,
covering January 1, 2023 through December 31, 2023. It includes particulate matter (PM2.5, PM10),
nitrogen dioxide (NO2), sulfur dioxide (SO2), ozone (O3), temperature, and relative humidity.

How it was created:
Values were generated as a realistic synthetic dataset designed for education, prototyping, and
method development. Seasonal patterns (winter heating/inversions; summer ozone peaks) and
random day-to-day variability were modeled.

Units:
- PM2.5, PM10, NO2, SO2, O3: micrograms per cubic meter (µg/m³)
- temperature: degrees Celsius (°C)
- humidity: percent (%)

Suggested uses:
- time-series analysis and visualization
- forecasting and machine learning baselines
- classroom demonstrations (regression, seasonality, anomaly detection)
